Abstract
Composite panels may be prepared using a moisture resistance additive having a formulation that includes a triglyceride having a saponification value of at least 150 and an iodine value of at least 35. The additive may be used in the form of a water emulsion. The water emulsion may be prepared by dispersing the components of the additive formulation under conditions sufficient to at least partially saponify the triglyceride. The moisture resistance additive can impart resistance to moisture absorption and thickness swelling to composite panels prepared therewith.
Claims14
A composite panel prepared using a moisture resistance additive useful for preparing composite panels, the composite panel comprising:
- gypsum, cellulose, or combinations thereof;
- and
- the moisture resistance additive, wherein the moisture resistance additive was provided as an emulsion comprising:
- from 10 to 50 weight percent of a triglyceride having a saponification value of at least 150 and an iodine value of at least 35;
- from 0.5 to 20 weight percent of a hydrocarbon wax;
- from 0.5 to 3 weight percent of a linear C12 to C22 fatty acid;
- and
- a compound or compounds selected from the group consisting of an amine, an inorganic base, and mixtures thereof, wherein the amine, when present, comprises from 0.5 to 3 weight percent of the emulsion, and wherein the inorganic base, when present comprises from 0.5 to 6 weight percent of the emulsion, and
- water;
- and wherein the emulsion is prepared under conditions sufficient to disperse components of the formulation and at least partially saponify the triglyceride.
A method for preparing composite panels comprising introducing a moisture resistance additive useful for preparing composite panels into a composite panel, the moisture resistance additive comprising:
- from 10 to 50 weight percent of a triglyceride having a saponification value of at least 150 and an iodine value of at least 35;
- from 0.5 to 20 weight percent of a hydrocarbon wax;
